T o all whom it may concern;

Be it known that 1, PETER Knuss, a (Ilt)izen of the United States,residing in the borough of Brooklyn, county of Kings, city and State ofNew York, have invented certaln new and useful Improvements in Machinesfor Beading and Flanging Can-Bodies, of which the following is aspecification.

in the making of tin cans it is customary to feed fiat sheets oftin cutto the required size successively to apparatus which first bends up anddown the opposite edges to form hooks; then advances the sheet to thepoint where it is folded around an expanding mandrel called the horn insuch man- .ner that the. hooked edges are inter-hooked,

whereupon the horn expands and draws these hookstogether, and a ramcalled the bumper then descends and squeezes the inter-engaging hooksagainst the horn to form the side seam otthe can. This ends the workpeculiar to the so-called bodyforming machine. The subsequentoperationsdepend upon the kind of can being made. For some purposes the can is hottomed at one end and receives a slip cover at the otherend or top. Formaking such cans it is desirable to form a head just beneath the coverto stiflen the upper part of the can. For applyii'ig the bottom theopposite end of the can has to bo flanged, that is, its edges turnedoutwardly in order that it may later be double-seamed to the bot tom.For some cans the bead, instead of being at the opposite end from theflange,

is adjacent to the same end.

The present invention provides a machine for performing simultaneously,or nearly so, these. operations of beading and Hanging.

The machine provided by this invention may receive the can brdy after itis delivcred out of. the brdy-forming machine; or

the two may be built together so that the can body, after thesidc-seammg operation, is

pushed along on a prolongation of the. horn the bead. Vhile the can isheld between the respective beading jaws whereby it is se-' curelyclamped, a flanging die is pressed against its projecting end,partlyentering. the can, and expanding its end portion, whereby it isturned outwardly to form the flange. The beading jaws are then retractedto free the can body and the Hanging die recedes carrying the can withit, whereby the can is advanced beyond the plane of the beading jaws,whereupon it is dropped out of the machine. To insure the movement ofthe can with the receding die one or more ejectors are. provided whichengage. the newly-formed flange and compel it to advance with theHanging die.

The accmnpanyinp drznvings show a machine embodying this invention, ofwhich- Figure 1 is a side elevation; Fig. 2 is. a vertical transversesection taken on the planes of lines in Fig. 1. Fig. 2 is a sectionalfragment of Fig. 2. Fig.3 is a vertical section taken mainly on theplane of the line 3-3 in Fig. 2. Fig. 4 is a fragmentary transversesection on a larger scale, giving a face view ofthc beading jaws. Fig. 5is a section in the planes of the'lines 5-5 in Fig. 4 shoeing themachine at the end of the heading and Smtllllflg operations. Fig. 6 is aface view of the heading jaws in their retracted or inactive position,the supporting parts being! omitted. Figsfi and 8 are a face view andplan of the wedge for expanding the inner. beading jaws. Figs. 9 and 10are a face view and horizontal section of one. of thesejaws. Fig. 11 isa fragmentary clcratirn similar o; part of Fig. 1, but showing themachine in a diffcrent position. Fig. 12 is a fragmentary elevationlooking in the direction "12' in Fig. 11.

In Fig. 1 let A represent the horn of the hoduforming machine, or anextension of such horn; or it may be any guide along which thesuccessive can bodies are fed by any suitable means. present inventionthey might be fed by hand. 15 shows a fragment of theframe of thelioitwl'ormiug machine; or it might be any other suitable su 'iportingframc\\-'ork.

is thr man: tramc of the present machine l is a shaft which may beregarded as the driving shaft and may carry a belt pulley or any othersuitable means for imparting 100. So far as concerns the. i

movement. As shown in 1 this shaft communi'ates motion through mitergears a a to a shaft E which in turn communicates movement through mitergears 2') to a shaft F. The shafts D and F revolve synchronously. Theshaft 1) carries an cecentric G (Fig. 3) which is encircled byeccentric'strap connecting by a link 0 to one arm of a lever d,.tl1eopposite or longer arm of which connects by a link 6 to any suitablepart of a slide H whereby this slide is reciprocated regularly by theoperation of the eccentric. The slide H slides in ways ,5. formed on thetop of the frame C, as best shown. in Fig. 2. The link 6 connects withan adjustable piece f clamped to the slide by a block 9 which isadjustable by a'screw whereby the slide may be set forward or backward,as may be required (see Fig. ,3).

The shaft F carries a cam J, the groove of which acts upon a rollercarried on the lower arm of a lever j, the upper arm of which connectsby a link I: to a yoke l engaging a rod K, which has sliding hearings inthe opposite endsof the slide H. For adjusting this rod longitudinallyset-nuts m m are provided. The front end of the rod is supported by aplate 11. fastened on the front of the slide H.

The fianging die L is carried on the front end of the slide H againstthe plate a and the rod K moves freely through a central hole in thisdie.

The beading mechanism comprises outer beading jaws M M shown as four innumber, which encircle the can, and inner beading jaws P P, (Fig. 6)also shown as four in number, which are adapted to'fit within the can.The outer jaws have in their inner faces a circumferential groove; andthe inner jaws have on their outer faces a similar but smallercircumferential rib in the same plane with said groove, so that when therespective jaws are forced together the rib-and groove cooperate to formthe bead. The inner jaws are supported by the end of the mandrel or hornA, (Fig. 5) being overlaid by 'a plate 7) fastened by screws to the hornor mandrel. Each jaw is confined to a radial movement by being formedwith a-rib 1", Figs. 9 and 10, which slides in a radial groove in theend of the mandrel A. The sections are moved by an expander Q, igs. 7and 8, which has essentially four wedge-shaped faces engaging the innerfaces of the four jaws. These faces are dovetails s engaging dovetailedgrooves s in the jaws, as shown in Figs. 8 to 10. The expander Q, ispressed out by a spring t to contract the jaws and is pushed in by therod K to expancl the jaws. The outer jaws M M, which are preferablyalternated in arrangement with the inner awsg" are also moved radiallyand simultaneously. They are shown in their inner positions in Fig. 4and in their outer pO-Sllltms in i- 5. The jaws are mounted on radialslides M mounted in a special .iratae R. The jaws are drawn outw rdly bysprings u They are forced inwardly by a cam ring S shown best in 6,which is given an oscillatory movement "wl'ioreby the cam surfaces ornotches '2: r are brought into or 'out of engz-igenient with rollers 1:o carriedon their respective slides M. The ring S is connected to an arm5 which connects by a rod T to a crank U conveniently carried on mitergear (12, Fig. l. ()n the downstroke of the crank a downward pull iscommunicated through the rod T which positively pulls down on the armi." and oscillates the ring S to the position where the cam notches'uvcoincide with the rollers '12, thereby opening the jaws M M as shownin Fig. 6. The opposite i'novement oscillates the ring to cause the camsv to force the jaws inwardly; and as in this 'a'iovement the grasp andembrace the can body, it is desirable, to allow for slight variations inthe diameter of the can or the thickness of the sheet metal, that thisactive movement of the ring 5 should be performed yieldingly in orderthat the jaws may not be pressed in too far. For this purpose theconnecting 10d T is made telescopic or collapsible, in. manner bestshown in. Fig. The rod is dividedintc two parts between which is a stiffspring S The upper part of the rod enters into a sleeve T making asliding fit therewith, while the lower partof the sleeve T isscrew-threaded and engages the threaded lower end of the rod. The sleevehas a slot into which projects a pin 10 carried by the upper section ofthe rod, the slot being sufliciently long to allow for the desiredyielding movement. In the down-stroke the end of the slot remains incontact with the pin 10 as shown in Fig. 2 and thus the movementimparted is positive; while on the up- SUOliQ the thrust is communicatedthrough the a ring J" and is yielding. For adjustthe length of theconnecting rod T the sleeve T is screwed up or down and locked by a nutto.

The operation is as follows :-A.ssuming the machine to be built as a.continuation of an ordinary can-body-forming machine, the can body fromthe latter is pushed along the horn Aby means of a reciprocating feedingpusher V, Fig. 5, or in any other manner. The can body is shown at X inFig. 5. The cam ring S in its oscillations then forces inward the jaws MM until they tightly grip the can'body and hold it, forming thereby anannular anvil. Meanwhile the slide H and rod K have been approaching thecan body from the right in Figs. 1 aud o, and before the fianging die Lreaches the can body the advancing end of the rod K strikes the expanderQ and pushes it back l to animov use tin; flanging die to opei'aie.
